We have been to parties at local jump facilities and so far Jump Planet is my favorite. It was a huge hit for my older kiddo, she still calls hand sanitizer "bouncy house" because when we go to Jump Planet they squirt it in her hands before going upstairs to the party room. They have two huge play areas that total over 6,000 square feet of jumping fun. They also have a younger area for the 3 and under siblings that jump not as high as their older siblings. Parties are great and well planned out in specified time slots and you can reserve 1 of the 2 sides of the gym for your party.
But, what I haven't done yet is go to a drop in time slot. On their website, you can view by month the days and times that are available for drop-ins. This is great because even though my children wish that every day is a birthday party, thankfully birthday parties are not that frequent. The rate is $6 for the first child and $4 for a sibling.
Go to their website to find the next rainy day that you may be looking for something to do.
They are located in Canyon Park and contact info is available on their website.
Go have a jumping good time!
